Using Service-Linked Roles for
Migration Hub

AWS Migration Hub uses AWS Identity and Access Management (IAM)
service-linked roles. A service-linked role is a unique type of IAM role that
is linked directly to Migration Hub. Service-linked roles are predefined by Migration
Hub
and include all the permissions that the service requires to call other AWS services
on
your behalf.

A service-linked role makes setting up Migration Hub easier because you don't have
to
manually add the necessary permissions. Migration Hub defines the permissions of its
service-linked roles, and the services that can assume its roles. The permissions
include
the trust policy and the permissions policy, which cannot be attached to any other
IAM
entity.

For information about other services that support service-linked roles, see AWS Services That
Work with IAM and look for the services that have Yes in
the Service-Linked Role column. Choose a Yes with
a link to view the service-linked role documentation for that service.
